ToaZZ whom it may concern:

Be it known that we, Faun BABNEY and WILLIAM J. GOURLEY, citizens of the Unitsd States, residing, respectively, at Fort 5 Worth, in the county of Tarrant and State of Texas, and at VVeatherf-ord, in. the county of Parker and State of Texas, have inyented certain. new and. useful Improvements Bearing Saddles for Pump'Jacksof which the following-is a specification,

Our invention relates to pumping and more particularly to saddles for the channel beams, and the' object to prevent the weakening of the. channel: beams by cutting holes through the beams. Another object is to provide saddles which are adjustable so that the fulcrum of the jack can be changed to any required adjustment.

Another object is to provide saddles which will brace the channel beams and which will not weaken the channel beams as in the old saddles which required holes made in the channels for bolts to secure the saddles. An advantage which is afforded by the improved saddles because in many cases smaller channel beams may be used, the beams not being weakened by holes through the beams. The saddle can be readily moved'or adjusted on the channel beams for the purpose of changing the stroke of the pumping mechanism.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a side elevation of a pump jack provided with our improved saddle. Fig. 2 is a vertical section of the channel beams with the saddle applied thereto. Fig. 3 is an enlarged side elevation of the saddle. Fig. 4 is a side elevation of the channel beams with a variation in the truss support located on the saddle. Fig. 5 is a plan view of Fig. 4.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show a pump jack frame of ordinarytype, having channel beams 1, upright frame members 2 and angular braces 3,. The saddle is composed of an upper FOB BUMP: Acxs.

The saddle members 4 and 5, haw; shoulders 7 for bracing the webs of the channel beams 1.- The saddle members 4 and5 have shoulders and shoulders 9 which brace the upper and lower members of the channel beams.

Lugs or pins or bolts 11 may be inserted in the clamping members and projected through the upper and lower members of the channel beams, as shown in Fig. 2, or set screws 12, as shown in Fig. 5, may be used to prevent the saddle from slipping on the beams 1. Wedges or keys 13 may be used for this purpose, as shown in Fig. 5. Y

The channel beams may be further braced by a truss 15 and bridge 14. The bridge 14 may be placed on the'beam or on the upper clamping member. ,See Figs. 1 and 4. The truss may be made adjustable to the bridge by using links in the truss, as shown in Figs. 4 and 5.

The clamping members 4 and 5 may be interchanged. The journals 6 wear very fast. A supply of the lower members 5 may be provided and the members 5 can be used nel beams, and bolts for clamping the saddle members on the channel beams.

2. A bearing saddle for pump jacks in combination with the channel beams of a pump jack comprising upper and ;lower members, said members having channels for receiving the upper and lower parts of the channel beams and having shoulders for bracing the webs of the channel beams, and means for clamping said members on the channel beams.

3. A bearing saddle for pump jacks in combination with the channel beams oi a pump jack comprising upper and lower members engaging the upper and lower parts oi the channel beams and having flanges for bracing the outwardly projecting flanges oil the channel beams and having shoulders for bracing the webs of the channel beams, and means for clamping said members on said channel beams.

4. A bearing saddle for pump jacks in combination with the channel beams of a pump jack comprising upper and lower members engaging the upper and lower parts of the channel beams and having means for bracing the outwardly projecting flanges of the channel beams and means for bracing the webs of the channel beams, means for clamping said members on the channel beams, and means for preventing said members from slipping on said channel beams.

5. A bearing saddle "for pump jacks in combination with the channel beams of a pump jack con'iprising upper and lower members engaging the upper and lower parts of the channel beams, means for preventing said members from slipping on said beams, and means for clamping said members on said channel beams. I

6. A hearing saddle for pump jacks in combination with the channel beams of a pump jack comprising upper and lower members engaging the upper and lower parts of the channel beams, means for preventing said members from slipping on said channel beams, means for clamping said members on said beams, and means for bracing said channel beams comprising a bridge member on the said upper member and a truss member engaging said bridge member and attached to said channel beams.

In testimony whereof, we set our hands this lth day of July, 1925.
